Title: Scroll type compressor
Inventor: ITOU MASAATSU
IPC: F04C18/02
Filed: 1981-05-12
Abstract: PURPOSE:To achieve the maximum suction gas capacity in spite of the small radius of revolution and the reduced number of turn, by forming the spiral shape of each spiral member such that it is connected linearly to a developed line or an arch. CONSTITUTION:The spiral shape of a fixed spiral member 1 or a movable spiral member 2 is constructed such that a linear line is connected to a developed line. Assuming the middle drawing is the spiral formed with the basic developed line while the lower drawing is the spiral of the invention assembling the linear line, the number of the spiral is two in both case having same movable scroll diameter, and the maximum suction gas capacity in each drawing is as shown by the slant, and when employing the linear line in the spiral and lengthening the length of the linear section in the spiral the maximum suction gas capacity can be increased without increasing the number of turn of the spiral nor the radius of the revolution.

IPC: B41J2/055
Filed: 1983-04-22
Abstract: PURPOSE:To make it possible to hold good image recording quality even under any temp. condition, by controlling a recording speed corresponding to the output of a detection apparatus for detecting a circumferential temp. CONSTITUTION:At an atmospheric temp., a bimetal 211 is not deformed and a timer A206 is connected to a comparator circuit 202. A timer 204 is set by the signal of an emitting position detector 205 and the output thereof is compared with a refill time Tr1 at an atomospheric temp. set by the timer A by the comparator circuit 202 and the comparison result is imparted to a drive circuit 201 to perform the adjustment of voltage to an ink jet head moving motor 106. Therefore, the speed of the motor 106 is controlled so that a head moves one recording pitch for the time Tr1 and the emitting frequency of the head is held to 1/Tr1 while a recording speed corresponds to the set value of the timer A. On the other hand, at a low temp., the bimetal 211 is deformed and a timer B207 is connected to the comparator circuit 202 by a change-over switch 210 to set a refill time at a low temp. By this method, good image recording quality can be held even under any temp. condition.

Title: Dry-distillation combustion furnace
Inventor: UENO SHINICHIROU
IPC: C10B53/00
Filed: 1978-06-12
Abstract: PURPOSE:To reduce the quantity of discharged dry-distillation residues, by providing a dry-distillation residue combustion zone under an air-shut-off vertical dry-distillation furnace to burn the residues by supplying air to the combustion zone. CONSTITUTION:Garbage is introduced into the top of the dry-distillation furnace 11 so that the garbage falls in the furnace. The garbage is dried by distillation while it is insulated from air by next-introduced garbage. At that time, the inflammable constituents of the garbage are pyrolyzed. As a result, the garbage changes into the residues. The residues falls into the residue combustion zone 21 as the temperature of the residues is about 800 deg.C. Air is supplied to the residues in the combustion zone so that the residues are burned to ash. The quantity of the dry-distillation residues is equal to one eighth of that of the introduced garbage. The quantity of the ash is equal to one third of that of the residues. Thus, the quantity of the discharged residues is greatly reduced. Inflammable gas is produced from the garbage with high efficiency.
